which element is represented by the following electron configuration: 1s²2s²2p⁶3s²3p² ?\n silver\n silicon\n sodium\n selenium
Answer
Explanation:
Step1: Calculate total electrons
Add up the exponents in the electron - configuration. $2 + 2+6 + 2+2=14$.
Step2: Identify element by atomic number
The atomic number of an element is equal to the number of electrons in a neutral atom. The element with atomic number 14 is silicon.
Answer:
silicon
